Abstract

Charging device for electric vehicles and provision of power supply in parking spaces where the parking lot is equipped with an electrical outlet for electric vehicles to connect electric vehicles for recharging batteries composed of devices that are installed in these vehicles and some conductive plates with which they are installed on the parking lot floor. In such a way that when you want to press a switch or automatically the devices lower electrical poles to the ground that make contact with the conductive plates by getting electricity to the vehicle for charging the batteries.

Description

The invention relates to a charging device for electric vehicles and an electrical outlet arrangement in parking spaces where the parking lot is equipped with an electric socket for electric vehicles.

The difference with regard to the parking with electric socket for vehicles is that the connection is made automatically when the car is stopped, which avoids the inconvenience of plugging and unplugging manually.

FIELD OF THE INVENTION

The present invention belongs to the sector of the auxiliary automotive industry as well as to the electrical components industry.

BACKGROUND OF THE INVENTION

With the arrival of electric cars, the problem arises of adapting towns and cities to the needs of these vehicles.

Thus many of these environments have been equipped with parking lots in which it is possible to leave the electric vehicle and plug it in, so that while it is parked the battery is charged.

Among them we can distinguish the European patent EP104186 for “Assembly of power from the ground for electric vehicles”, requested by INNORAIL (France) and which refers to:

           Ground power assembly for electric vehicle, comprising

a series of contact track segments (210, 220), isolated from each other and at least

partially discovered, a power line (230) intended to be powered

permanently, means (700) suitable for selectively connecting the

track segments (210, 220) to the power line (230), as well as support segments (100) each having the general shape of a profile comprising, in one piece, a top horizontal wall (107) that it receives on its upper face a track segment (210, 220), and a soul that receives the power line (230), characterized in that the soul forms an electrical insulator around the power line and discovers it at the end level of the support segments (100), and because the assembly comprises at least one helmet (310, 320) adapted to rest on its free edges against the sides of the souls of two support segments

(100) consecutive, sealing the uncovered parts of the feed line at the level of the adjacent ends of the two support segments.

As can be seen from its careful reading and drawings, this invention does not contemplate the device of the vehicle and the same device installed is totally different in conception and realization of the one recommended in the invention.

Also the inventor has detected the existence of another antecedent, the document WO2010009502, in the name of Vicente Manuel Sánchez Segarra called "System to facilitate the recharging of a vehicle" whose summary reads:

The system is composed of a sealed module (1) connected by wiring to the internal communication network (2) of the vehicle and to the conventional BSI module (3) in an electric vehicle, in order to enable or disable the passage of the electric current, coming from the conventional power grid or other energy source attached to the vehicle, to charge an electric battery in the vehicle and ensure the collection of the amount of electric current drawn from the power grid or from the attached energy source Upon receiving a confidential code of a payment method.

We also note in this background that it is a conventional wiring, not a telescopic device such as the one presented in the patent, and also incorporates payment methods that are not claimed in this requested patent.

Currently the vehicles are equipped with a plug and cable for charging and it is necessary to remove the cable and plug. When we want to leave we must unplug and store the cable.

This causes inconvenience and it is unsightly and dangerous to leave the cables in sight as they can cause accidents.

To avoid these problems, a system has been designed in which one part will be adapted to the vehicle and another in the parking area that allows the connection to be made automatically.

DESCRIPTION OF THE INVENTION

The system has automatic devices adapted to the vehicle and plates installed on the floor of the parking area. These devices are automatically responsible for lowering two electrical outlets on the bottom of the car that will contact two electrically charged plates.

The devices can be operated by means of a button from inside the car.

In this way, when parking in these car parks, it is only necessary to press the button and automatically lower the connection terminal to make contact on the plates and start charging.

This invention can also be used in traffic lights, so that while standing on them it can be used and loaded. For this it is necessary to install plates in a few meters in the traffic light stop areas.

The plates that will be placed on the ground will have low voltage electricity so as not to cause electrical hazards.

That low voltage will be converted by an inverter installed in the car at the voltage and intensity required for the correct charging of the batteries

The boards can be connected to a payment and time control system, and turned on. .

PREFERRED EMBODIMENT OF THE INVENTION

The invention relates to a charging device for electric vehicles and an electrical outlet arrangement in parking spaces where the parking lot is equipped with an electric socket for electric vehicles.

The difference with regard to the parking with electric socket for vehicles is that the connection is made automatically when the car is stopped, which avoids the inconvenience of plugging and unplugging manually.

In a more detailed way the charging device for electric vehicles is constituted by the following elements:

.- mechanism box (1), consisting of a box with the rear metal wall (2) that has mounting holes (5) for fixing in the most appropriate place of the vehicle and a plastic cover at the top (3) where the control board and buttons (4) of the mechanism are located.

The mechanism box (1) has insulating elements (6) at the bottom, in case it had to be fixed to a metal area of the vehicle, such as the chassis, that did not have problems of load diversion and avoid short circuits.

Inside the mechanism box (1) there is an electric motor (a) that moves a toothed reel (b) by means of an endless gear (h) assisted by a pulley with friction clutch (c).

The toothed reel (b) has a cable wound (g) that runs through the inside of a telescopic tube (t) that comes out from the bottom of the mechanism box (1) and said cable

(g) at its end part l carries a spring (f) and at its end a connection terminal (j) which will come into contact with the load plates (23).

At the lower end of the telescopic tube (t) will be the spring (f) that will be compressed, so that in the case of car movements, always make contact with the ground. It also helps adapt to possible differences in vehicle height.

The telescopic tube (t) has a circuit closure part (i) on top of it, so that when the tube (t) is fully retracted for the motor (a), and the telescopic tube (t) is also a pole connection (e) and an output pole (k) of current to the vehicle's batteries

The electrical outlet arrangement in parking spaces where the parking lot is equipped with an electrical outlet for electric vehicles is constituted by two conductive plates (23) located on the floor of the parking space (20), you separate these spaces by a barrier of separation (22) so that the vehicles are correctly positioned in relation to the loading device.

The conductive plates (23) are assisted by an apparatus (24) that functions as a payment, time control and start-up system that receives the current when activated and sends it to the conductive plates (23).

The electric current sent to the conductive plates (23) will be low voltage so as not to cause electrical hazards.

When the vehicle is placed above a parking space (20), provided with conductive plates (23), it first activates the charging device by contacting the connection terminal (j) with the conductive plate (23).

From that moment it acts on the apparatus (24) to provide power to the assembly.
